Abstract: A system and method are described for validating an IoT device. For example, a method in accordance with one embodiment comprises: generating a first random value to be used as a first offset into a first block of program code of an Internet of Things (IoT) device; transmitting a challenge request message to the IoT device, the challenge request including the first offset or data based on the first offset; receiving a challenge response message transmitted by the IoT device, the challenge response message comprising first authentication data for the first block of IoT device program code; and using the first authentication data to attempt to validate the first block of program code.

Abstract: A system and method are described for implementing latched attributes within an IoT system. For example, one embodiment of a method comprises: specifying an attribute for each of a plurality of items of data managed in an Internet of Things (IoT) device and/or an IoT service, at least some of the attributes comprising latched attributes having a current value and an indication of state changes to the latched attribute over a period of time; when an IoT device is unable to connect with the IoT service for a period of time maintaining an indication of any state changes occurring to the latched attribute over the period of time; upon establishing a successful connection between the IoT device and the IoT service after the period of time, transmitting the indication of state changes of the latched attribute from the IoT device to the IoT service; and analyzing the indication of state changes to determine whether to generate an alert condition on the IoT service.
